SAFETY

WARNING

Never drive close to the edge of a gully or steep embankment that may collapse and cave-in, causing the machine to tip.

• Shift to a LOW gear before descending a steep hill, to assist in braking and improving your control of the machine.

Use engine braking to reduce speed before

applying the tractor brakes.

• Never coast down a hill, run-away machines are liable to tip.

• Slow down and exercise caution when making turns and changing direction on a slope.

Stopping Operation

• Before stopping the engine: Reduce the engine speed to ‘SLOW’ and let it operate at ‘no load’ for five to ten minutes, to allow the engine to cool down.

To safely park the machine:

• Stop it on level ground, move all controls to the ‘OFF’ position. Lower the Cutter Head and Forks to the ground. Put the transmission in NEUTRAL, apply the brakes and stop the engine. Before leaving the operator’s seat, wait for the engine and moving/rotating parts to stop. Remove the ignition key.

To free a ‘mired’ machine.

• Check that all towing devices are of adequate size/strength to handle the load.

• Always attach to the Draw Bar of the towing unit. Do not use the front attachment point. Apply power smoothly to take up slack, a sudden pull could ‘snap’ the towing device causing it to ‘whip’ or ‘recoil’ dangerously.

Caution should be exercised when attempting to free a machine that is stuck in mud. Hazards that can occur when towing, and are to be avoided are:

• The towing tractor overturning.

• The tow chain failing and recoiling. (Use of a

cable is not recommended).

• Tow-bar failing.

• The harvester becoming unstable and tipping.

1-04

The following procedures are recommended;

• If possible reverse the machine out, if it is ‘mired’ in mud.

• Dig mud out from behind the wheels. Place boards behind/under the wheels and reverse out ‘slowly’. Keep bystanders clear of the

rear of the machine

• Dig mud out from in front of the wheels and drive ahead ‘slowly’.

Maintenance Safety WARNING

Do not service or repair this machine with the attachments in the raised position, unless they are securely blocked, or the safety devices are engaged. Failure to do so could result in serious injury or death. Do not enter the Forks/Piling Ca vit y area when the engine is running.

• To attain maximum saf et y and the optimum harvesting results, maintain your RoboMax Harvester according to the recommended schedules and instructions in this manual.

• When servicing or operating the machine do not wear loose clothing or jewelry that can entangle in machinery and cause personal injury.

• Never allow untrained persons to operate or service the machine.

• Allow the engine and rotating/moving parts to come to a complete stop before attempting any service or repair work.

• Disconnect the battery cables before making any repairs, and before doing any welding on the machine. Disconnect ‘negative’ first, then ‘positive’. Reconnect in the reverse order.

• Carefully release pressure from components with ‘stored’ energy.

• Park the machine on smooth, firm, level ground.

• Replace worn, damaged, or faulty parts with parts supplied by the manufacturer.

• Before working on the machine, lower the

Cut-Off Blade

If the Cut-Off Blade ‘A’ do the sod when the Spring Shaft is in the desired location, reposition the Cut-Off Blade Frame ‘B’ o on the Cut-Off Frame ‘C’. The Cut-Off Blade depth is reduced over time by wear, and by sharpening. If a blade is less than 2 ½ inches in depth, it must be replaced. Check that the edge of the Cut-Off Blade Mount ‘D’ do not hit the sod, on the ‘down’ stroke, as this will damage the sod and cause problems when the sod is ‘laid’.

NOTE

A Serrated Blade is available for use in soft soil, or excessive thatch. This Blade will give a cleaner more positive cut.

The Urethane Tension Straps ‘E’, allow the Blade to ‘swing’ with the forward travel of the machine as the cut is made. When the machine is stationary the Blade should hang in the vertical position. Any Change to the shape, or position, of the Tension Straps attaching hooks, will change the angle of the blade.

Pitch Angle

Pitch Angle is the angle that the Cutter Blade makes relative to the ground. The Pitch Angle is set at the factory for average cutting conditions. Pitch Angle can be adjusted to improve cutting performance in soft or hard soils. In soft conditions the Pitch Angle should be set so that the Cutting Blade is almost ‘parallel’ to the ground. In hard soil the Blade Angle should be increased, this maintains the correct cutting angle, and also prevents the Cutting Head from coming out of the ground.

IMPORTANT

When the Pitch Angle is changed, the relationship of the Cutting Blade to the Conveyor Mat, and also the Ground Roller, must be maintained. The Front Idler Shaft of the Conveyor Mat can be adjusted to ensure that there is no interference between the Mat and the Blade. Refer to the Ground Roller adjustment instructions for the correct Roller to Blade set-up.

Roller Adjustment.

The Ground Roller ‘D’ supports Conveyor. It also applies pressure to the sod ahead of the Cutter Blade ‘E’. The Roller position can be adjusted ’forward’ or ‘back’ on the Cutter Head Frame, it must be positioned with the vertical centerline of the Roller is 2 ½ inches ahead of the Cutter Blade, when the Blade is at its maximum forward stroke. The Roller and Blade must be parallel to each other, avoid ‘tapered’ rolls. The Roller must be ‘centered’ between the Cutter Side Arms, to prevent the attaching bolts ‘F the Roller.

In ‘Peat’ or ‘Muck’ soil conditions the 2 ½ inch dimension, from Roller Center to Blade, may need to be reduced to maintain the proper cutting action. In ‘soft soils’ or ‘excessive thatch’, ‘rolling’ the area to cut, before harvesting, will result in easier cutting and a better quality, tighter roll.

In ‘stoney ground’ conditions it is advisable to move the Roller ‘forward’, to allow small stones to pass between the Blade and the Roller.The increase in clearance can be up to 2 or 2 ¼ inches. Insufficient clearance from Roller to Blade, causes a ‘pinching action’, resulting in pieces of sod that are longer than required

Ground Roller Scraper.

The cut length of the sod is measured by the rotation of the Ground Roller ‘D’. Th The build-up of grass, mud or dirt, on the Roller, can increase its diameter, resulting in an increase to the length of cut. The Roller Scraper ‘G is provided by ‘slotted’ holes. Loosen the fasteners ‘H’ and pivot the Scraper until it is ‘just’ clear, (1/32in.), of the face of the Roller.
